A new tool developed by MIT researchers could help violin designers test how an instrument might sound when certain dimensions or properties are changed without even pulling out a bow, reports Jennifer Ouellette for Ars Technica. The researchers crafted a virtual violin, “a computer simulation tool that can capture the precise physics of the instrument and even reproduce a realistic sound of a plucked string,” Ouellette explains.
Researchers from MIT have created a new model that can predict wave behavior on different planets, reports Kristen French for Nautilus. “On Earth, waves form as wind drags across bodies of water, pushing unevenly on their surfaces. As the waves lengthen, and the distance between crests grows, the waves are increasingly driven by the force of gravity rather than by surface tension,” French writes. “On faraway planets, the size of the waves would depend not only on the strength of gravity and the speed and direction of the wind, but the density of the atmosphere, the viscosity of the liquid in the oceans and lakes, as well as the depth of the bed. All these factors were fed into the PlanetWaves model.”
MIT scientists have developed a new model, dubbed "PlanetWaves," that predicts wave behavior on different planets, showing that the "smallest gust of wind on Titan could generate huge, roiling waves across seas of hydrocarbons," reports Andrew Paul for Popular Science. “PlanetWaves is far more than a novel simulator,” writes Paul. “Calculating fluid behaviors on distant planets and moons could help inform engineers building new spacecraft and probes.”
Writing for Meteorological Technology International, Alex Pack explores how MIT researchers have developed a new “lightning-prediction model that could help protect more unconventional aircraft designs – such as blended-wing bodies or truss-braced configurations – as aviation moves beyond traditional tube-and-wing designs.”
Researchers at MIT have developed a new method that can predict how plasma will behave in a tokamak reactor given a set of initial conditions, reports Gayoung Lee for Gizmodo. The findings “may have lowered one of the major barriers to achieving large-scale nuclear fusion,” explains Lee.
MIT astronomers have found evidence that a massive asteroid impact billions of years ago “may have briefly amplified the moon's old, weak magnetic field, leaving behind a magnetic imprint still detectable in lunar rocks,” reports Sharmila Kuthunur for Space.com. “While the moon once had a weak magnetic field generated by a small molten core, the team's research suggests it likely wouldn't have been strong enough on its own to magnetize surface rocks,” Kuthunur explains. “However, a massive asteroid impact may have changed that — at least briefly.”
Ars Technica reporter Jennifer Oulette writes that MIT researchers have found that a “large asteroid impact briefly boosted the Moon's early weak magnetic field—and that this spike is what is recorded in some lunar samples.”
Materials World reporter Sarah Morgan spotlights how MIT researchers have “combined the waterproof stickiness of mussel-inspired polymers with the germ-fighting properties of mucus-derived proteins, mucins, to form a cross-linking gel that strongly adheres to surfaces.” The new adhesive could be used to coat medical implants to prevent infection and bacteria build-up. Postdoc George Degen explains: “We demonstrate adhesion to wet tissue and metal-oxide surfaces, important substrates for biomedical applications. Moreover, our mucin-derived hydrogels discourage the formation of bacterial biofilms, raising the possibility of antifouling coatings.”
Researchers from MIT have “identified genes that the tuberculous bacteria rely on to survive and spread,” reports Allison DeAngelis for STAT. “Until now, very little was known about how tuberculous bacteria survived temperature changes, oxygen levels, humidity, and other environmental factors during the journey from one person’s lungs to another’s,” explains DeAngelis.
Mohamed Elrefaie speaks with Automotive World reporter Will Girling about his work developing an open-source dataset of 8,000 car designs, including their aerodynamic characteristics, which could be used to develop novel car designs in a more efficient manner. “If an automaker wants to reduce drag and improve performance, it can guide the GenAI model to produce those specific designs,” Elrefaie explains. “The standard development cycle for a design using legacy tools can take anywhere from three to five years, as it requires collaboration between many specialized departments. With AI, you could validate up to 600 designs in just one or two minutes.”
MIT scientists have developed a new model to analyze movements across the Antarctic Ice Sheet, “a critical step in understanding the potential speed and severity of sea level rise,” writes Ava Berger for The Boston Globe. “The flow of glaciers is really the thing that could lead to catastrophic sea level rise scenarios,” explains Prof. Brent Minchew. The findings take “a really big and important step toward understanding what the future is going to look like.”
Researchers from MIT have developed “sustainable, offshore, hydrodynamic,” artificial reef structures capable of dissipating “more than 95% of an incoming wave’s total energy,” reports Nick Warburton for Materials World. The design “comprises vertical cylinders with four rudder-like slats attached to them, so that water can flow through the structure to generate 'swirling masses of water' or large eddies,” explains Warburton.
MIT scientists have found that lakes and seas made of methane may have shaped Titan’s shores, writes Jess Thomson for Newsweek. “This discovery could allow astronomers to learn even more about the conditions on Titan,” writes Thomson. “Knowing that waves carved out the coast enables them to predict how fast and strong the winds on the moon are and from which direction they blow.”
Gizmodo reporter Passant Rabie spotlights new research by MIT geologists that finds waves of methane on Titan likely eroded and shaped the moon’s coastlines. “If we could stand at the edge of one of Titan’s seas, we might see waves of liquid methane and ethane lapping on the shore and crashing on the coasts during storms,” explains Prof. Taylor Perron. “And they would be capable of eroding the material that the coast is made of.”
Researchers at MIT and elsewhere have found that the sun’s magnetic field “could form much closer to the star’s surface than previously thought,” reports Will Sullivan for Smithsonian Magazine. “The findings could help improve forecasts of solar activity that can affect satellites, power grids and communications systems on Earth—and produce magnificent auroras,” explains Sullivan.
